Senior Geotechnical / Environmental Consultant
Posting Date - 20 Mar, 2026
STM Environmental Consultants is growing, and we’re looking for an experienced Senior Geotechnical / Environmental Consultant to join our team.
Based in Twickenham, we are a well-established geo-environmental consultancy delivering high-quality environmental and geotechnical solutions to a wide range of clients.
While STM operates independently with its own strong reputation and client base, we are also part of a wider group of geo-environmental companies. This means you benefit from the best of both worlds — the close-knit, supportive environment of a specialist consultancy, alongside the backing, collaboration opportunities, shared expertise, and increased project exposure that come from being part of a larger group.
At STM, you’ll take real ownership of projects from day one, working within a collaborative team that genuinely values professional growth and technical excellence.
The Role
You will lead and manage geo-environmental site investigations while playing a key role in client liaison, regulatory engagement, and business development.
This is an ideal opportunity for someone ready to step into (or further develop in) a senior position with project leadership and people management responsibility.
- Project managing geo-environmental site investigations
- Producing and reviewing factual and interpretative reports
- Peer reviewing technical reports
- Liaising with Local Authority regulators
- Preparing quotations and supporting business development
- Managing and mentoring junior staff
Skills & Experience Required
- Extensive experience in:
- Geotechnical ground investigations
- Contaminated land risk assessments
- Excellent technical report writing skills
- Experience managing projects and people
- Strong communication and client-facing skills
- Minimum 5 years’ relevant experience
Qualifications
- Degree (BSc or MSc) in Geo-Environmental Science, Engineering, or related discipline
